Однако эта фурма не снабжена устройством, предотвращающим проскок пламени от сопел к смесительному узлу. Горение |смеси газа и кислорода внутри межтрубного подвод щего тракта приводит к резкому уменьшению пропускной способности фурмы по дутью и выходу ее из стро .В предложенной газо-кислородной фурме, с целью предотвращени проскока пламени из продувочных сопел в топливно-кислородный тракт, последний в нижней части разделен кольцевой водоохлаждаемой перегородкой с отверсти ми (кольцевую перегородку изготовл ют металлической, папример из меди), под перегородкой размещен кольцевой газовый коллектор, сообщающийс с продувочными соплами.На фиг. 1 изображена газо-кислородна |)урма в разрезе; на фиг. 2 — то же, разрез по А—А на фиг. 1.Описываема фурма состоит из трех коак- сиальпо расположенных труб, по которым, каки в обычной кислородной фурме, в головку I подаетс , а из нее отводитс вода, а также подаетс в нее продувочный газ. Фурма имеет центрально-осевой подвод воды 2 к головке I 5 на охлаждение, каналы 3 дл отвода воды из цеитральной полости головки в межтрубную полость 4 фурмы. Каналы 3 расиоложены равномерно между соплами 5.

Кроме того, в хвостовой части фурмы на15 уровне иатрубка 9 располагаетс смесительное кольцо 10, которое перекрывает межтрубный зазор, образованный центральной (осевой) трубой 11 и разделительной трубой 12. Смесительное кольцо 10 герметично сочлен етс 20 (например, с помощью сварки), привариваетс или с одной из этих труб или с обеими. В первом случае стыковка по окружности с трубой имеет уплотнение 13. Смесительное кольцо 10 содержит в себе р д вертикальных отвер-25 стий — смесительных сопел 14, через которые из верхней части 15 межтрубного зазора, перекрытого кольцом 10, кислород проходит в топливно-кислородный тракт 16.
